The slope of the given equation of the straight line is - 5/4.
We know that the direction of a line is defined by its slope. The slope is calculated by dividing the difference between the y-coordinates of two points on a line by the difference between their x-coordinates.
Here the equation of the line is
y = - (5/4)x - 1.
At x = 0, y = -(5/4) × 0 - 1 = -1
and at x = 4, y = -(5/4) × 4 - 1 = - 5 - 1 = -6
Now the slope = (-6 - (-1))/(4 - 0) = (-6 + 1)/4 = - 5/4
Therefore the slope of the given equation of the straight line is - 5/4.
